SDL_wcsncmp(3)

NAME
SDL_wcsncmp - Compare two wide strings up to a number of wchar_t values.

SYNOPSIS
#include <SDL3/SDL_stdinc.h>

int SDL_wcsncmp(const wchar_t *str1, const wchar_t *str2, size_t maxlen);

DESCRIPTION
This only compares wchar_t values; it does not care if the string is well-formed UTF-16 (or UTF-32, depending on your platform's wchar_t size), or uses valid Unicode values.

Note that while this function is intended to be used with UTF-16 (or UTF-32, depending on your platform's definition of wchar_t), it is comparing raw wchar_t values and not Unicode codepoints: maxlen specifies a wchar_t limit! If the limit lands in the middle of a multi-wchar UTF-16 sequence, it will only compare a portion of the final character.

maxlen specifies a maximum number of wchar_t to compare; if the strings match to this number of wide chars (or both have matched to a null-terminator character before this count), they will be considered equal.

FUNCTION PARAMETERS

str1
    the first string to compare. NULL is not permitted!

str2
    the second string to compare. NULL is not permitted!

maxlen
    the maximum number of wchar_t to compare.

RETURN VALUE
Returns less than zero if str1 is "less than" str2, greater than zero if str1 is "greater than" str2, and zero if the strings match exactly.

THREAD SAFETY
It is safe to call this function from any thread.

AVAILABILITY
This function is available since SDL 3.2.0.
